Question:
In uniform circular motion, the factor that remains constant is:
In uniform circular motion, the factor that remains constant is:
Updated On: Jul 12, 2022
- acceleration
- momentum
- kinetic energy
- linear velocity
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
As in uniform circular motion, the velocity is constant quantity
The kinetic energy is
$K=\frac{1}{2} m v^{2}$
It is a scalar quantity therefore, kinetic energy is also constant.

Notes on Motion in a plane
Concepts Used:
Motion in a Plane
It is a vector quantity. A vector quantity is a quantity having both magnitude and direction. Speed is a scalar quantity and it is a quantity having a magnitude only. Motion in a plane is also known as motion in two dimensions.
Equations of Plane Motion
The equations of motion in a straight line are:
v=u+at
s=ut+½ at2
v2-u2=2as
Where,
- v = final velocity of the particle
- u = initial velocity of the particle
- s = displacement of the particle
- a = acceleration of the particle
- t = the time interval in which the particle is in consideration
